SPOOL-HOLDER FOR BRAlDING-MACHINES.

SPECIFICATION forming' part of Letters Patent No. 632,534, dated September 5, 1899.

Application fil'ed January 80, 1899. Serial No. 703,789. (No model.)

T ctZZ witam, it may concern: Be it known that I, EWALD lWIUNDT, a citizen of the United States, residing at New York, in the borough of Manhattan and State of New York, have invented certain new and useful Improvements in Spool-Holders for Braiding-Wlachines, of which the followingis a specification.

This invention relates to certain improve- Io m en ts in spool-holders for braiding-machines,

by which the frietion of the thread along the bobbin in unwinding is obviated and the sliding up of the spool on the spindle prevented,

so that for these reasons the size of the spool can he considerably enlarged and a greater quantity of thread wound on the same.

The invention consists of a spool-holder for braiding machines comprising' a standard having a tension-eye, a spindle, a spool on zo the latter, an arcuate guard-plate spanning the periphery of the spool from a point adjacent to the tension-eye, said guard-plate having an outer thread-guiding surface, a leading-on edge and a leading-offedge,'and means against which the upper end of the guardplate abuts, all as will be hereinafter particularly described in detail and then pointed out in the claims.

In the accompanying drawings, Fgure 1 represents a side elevation of my improved spool-holder for braiding-machines. Fig. 2 is a horizontal section on line 2 2, Fig. 1. Fig. 3 is a side elevation of the upper part of the spool-holder, partly in section, through the locking-latch of the same, drawn on a larger scale. Fig. is a plan view of Fig. 3, and Fig. 5 is a perspective view of the latch shown as removed from the spool-holder.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A represents a spool on' which the braid-forming thread is wound, and C a spindle which is mounted on a base F, that is provided with top and bottom plates F' F2 and a Vertical plate F3 between the same, which plates serve to guide the spool-holder in the serpentine groovesin the base-plate of the braiding-machine. To the top plate F' is attached the upright standard B, which serves as a guide for the tension-weight B' of the thread.

On the lower part of the spindle Cis placed a disk D, which serves as the support forthe spool A. The diskD is provided withasleeve d, that rests on the base F. Around the spool and concentric with the spindle is arranged an arcuate guard-plate G, which is attached to the disk D and which is made of suitable sheet metal.

The upper end of the spool A is provided with teeth a, which are engaged by a pawlp, that slides' freely on the upper part of the standard B whenever it is lifted by the upward motion of the tension-weight, so as to intermittently remove the same from the teeth of the spool and permit the turning of the latter and the supply of thread to the braid made on the machine. The thread is ledv from the. spool over Vthe leading-on edge of the guard-plate G and around and upon its outer surface, from whence it passes o if of the leading-off edge located nearest to a hole 0 in standard B, through said hole o, then through the tension-eye b' of the weight B', and lastly through the tension-eye e in the locking-latch E at'the upper end of the standard B. The guard-plate G has a broad surface, so that the leading-on edge is located at a considerable distance from the leadingoff edge, th'ereby enabling it to span quite a portion of the periphery of the spool.

The locking-latch E is clearly shown in Figs.

3, 4, and 5, and consists of an angular plate that is locked at about its middle by means of a slot e' therein, said latch at one end of said slot entering a recess e in the upper end of spindle C, while a projecting heel 82 at its angle fits into a recess 83 of the standard B and the centrally-recessed upper end of the latter into side recesses 84 of its eye-carrying end, its other end abutting against the' inner surface of the guard-plate G. The lookinglatch connects the standard B, spindle O, and guard-plate G, and holds the spindle rigidly in position,while it forms an abutment 01' sup' support for the upper end of the guard-plate.

ly arranging the guard-plate concentrically around the spool and conducting the thread around the same the Vertical sliding motion of the spool on the spindle is entirely Ioo dispensed with and the spool enabled to follow freely the motion of the .thread as it unwinds upward or downward from the spool Without exerting any friction on the bobbin, the guard-plate neutralizing the friction to which the thread was heretofore subjected in nnwinding from the spool. The spool is therefore not liable to slide upon the spindle'nnder the tension of the thread and can therefore be made longer in size, so as to permit the winding of a much greater qnantity of thread on the same, While the easy and almost frict-ionless motion of the spool is produced. As the locking-latch can be readily detached from the standard and spindle on pressing the upper end of the spindle side-v wise in the slot e', the empty spool can be readily removed from the spindle and replaced by a full spool when the latch is replaced into position'for looking the parts together.

I-Iaving thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A spool-holder for braiding-machines, ccmprising a standard having a tension-eye, a spindle, a spool on the latter, an arcuate guard-plate, spanning the periphery of the spool from a point adjacent to the tensioneye, said guard-plate having an outer threadguiding surface, a leadin g-on edge and a leading-of edge, and means against which the upper end of the guard-plate abuts, substantially as set forth.

2. A spool-holder for braiding-machines, comprising a standard having a tension-eye, a spindle, a disk on said spindle, a spool on the latter, an arcuate guard-plate rising from said disk, and spanning the periphery of the spool from a point adjacent to the tensioneye, said guard-plate having an outer threadguiding surface, a leading-on edge and a leading-off edge, and means supported at the Vupper end of said spindle, against which the upper end of said gnard-plate abu ts, substantially as 'set forth.

3. In a spool-holder for braiding-rnachines, the combination of a standard, aspool-spindle, a guard-plate located on the opposite sidev of the spindle from the standard, and alocking-latch interlocking with the upper ends of the spindle and standard, said guard-plate abutting against the end of said latch, sub- I stantially as set forth. i

4. In a spool-holder for braiding-machines, the combination of a standard, a spindle, having a recessed upper end, a disk on said spindle, a spool supported on said disk, a gnardplate attached to said disk and extending around the spool, and an angular lookinglatch, connecting the upper ends of the standard and spindle, said locking-latch having a side recess and a projecting heel interlocking EWALD MU DT.
